Default installed base information can be modified from within an RMA, just like a sales order.

Setting the Edit Installed Base field to Yes in RMA/RTS Control lets you edit installed base information within the RMA via a pop-up window.

Information defined in Call Maintenance sets up default values related to installed base update, but the updates themselves normally take place in Call Activity Recording. It is still possible, however, to close calls and update the installed base directly from Call Maintenance. In the normal life cycle of a call, some activity is recorded for each line in Call Activity Recording. Processing in CAR can update the installed base in three ways: the call line item, any items issued to repair it, or any items returned.
